[GNC] Register issues within 3.2

[Alun Champion]

OS: MacOS
Version: Gnucash 3.2

After pasting (Cmd-V) data into a register the register will no longer
receive normal keyboard input, just the annoying keyboard beep.

Enter still works, as does tab but no data entry from the keyboard in any
field in the register for that account. Other registers for other accounts
continue to receive input (unless you paste something into that register).

This is very annoying because I often paste data from online account data.
